| Abstract: | A process for obtaining Sr0.3-3y/2LayBa0.7Nb2O6 (LSBN) ceramics at different concentrations of the La3+ cation and different sintering times is presented. The dielectric properties of the LSBN system where Sr2+ ions are substituted by La3+ cations follow the pattern of a modification by cationic substitution for a constant Sr/Ba ratio. This behavior of the dielectric properties indicate that the La3+ cations occupy the A(1) as well as the A(2) sites which favors the formation of the LSBN system up to y < 0.05. For higher values the dielectric properties of the ceramic start to deteriorate. Copyright (C) 1997 Published by Elsevier Science Ltd |
